The research aims to enhance the optical/electrical properties of Poly(3,4-ethylene dioxythiophene): Poly(styrene sulfonate) (PEDOT:PSS) conductive film with 0.2, 0.4, and 0.6 wt% (weight percentage) of nanographene thin film made via solution method with a post-treatment of Ethylene Glycol. The effect of nanographene particle concentrations on sheet resistance, optical transparency, and electrical conductivity behaviour of PEDOT:PSS conductive film is investigated, and its results are compared. Based on the investigational results, the PEDOT:PSS conductive film merged with 0.6 wt% of nano graphene thin film layer is found reduced sheet resistance, better optical transparency, and high electrical conductivity characteristics. PEDOT:PSS conductive film with 0.6 wt% of nanographene has found 275 Ω/sq sheet resistance value, improved optical transparency value of 75%, and 2210 S/cm is measured as electrical conductivity. The PEDOT:PSS conductive film with 0.6 wt% of nanographene thin film is the best scope for electronic applications, including touch screens and sensors.

摘要

The research aims to enhance the optical/electrical properties of Poly(3,4-ethylene dioxythiophene): Poly(styrene sulfonate) (PEDOT:PSS) conductive film with 0.2, 0.4, and 0.6 wt% (weight percentage) of nanographene thin film made via solution method with a post-treatment of Ethylene Glycol. The effect of nanographene particle concentrations on sheet resistance, optical transparency, and electrical conductivity behaviour of PEDOT:PSS conductive film is investigated, and its results are compared. Based on the investigational results, the PEDOT:PSS conductive film merged with 0.6 wt% of nano graphene thin film layer is found reduced sheet resistance, better optical transparency, and high electrical conductivity characteristics. PEDOT:PSS conductive film with 0.6 wt% of nanographene has found 275 Ω/sq sheet resistance value, improved optical transparency value of 75%, and 2210 S/cm is measured as electrical conductivity. The PEDOT:PSS conductive film with 0.6 wt% of nanographene thin film is the best scope for electronic applications, including touch screens and sensors.
